Eruptive History

The Global Volcanism Program is not aware of any Holocene eruptions from Douglas. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Douglas page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

Deformation History

There is data available for 1 deformation periods. Expand each entry for additional details.


Deformation during 2005 - 2010 [Uplift; Observed by InSAR]

Start Date: 2005 Stop Date: 2010 Direction: Uplift Method: InSAR
Magnitude: 6.000 cm Spatial Extent: 15.00 km Latitude: 59.000 Longitude: -154.000

Remarks: An uplift signal between Fourpeaked and Douglas is either due to magma or isostatic rebound.

Figure (see Caption)

(Left column) Observed (a, c, e, g) deformation images of Fourpeaked and Douglas volcanoes from four InSAR images from four different tracks. (Right column) Modeled (b, d, f, h) deformation images for the corresponding interferograms in the left column, showing LOS displacements predicted by a Mogi source located *7 km BSL. A full cycle of colors (i.e., one interferometric fringe) represents 28 mm of LOS surface displacement. Areas of loss of InSAR coherence are not colored
